LlNOTYPE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 619,441, dated February 14, 1899.

Application filed November 9, 1898. Serial No. 695,946. (No model.)

To all whom it may concern:

Be it known that I, JOHN R. ROGERS, of New York, (Brooklyn,) county of Kings, and State of New York, have invented a new and useful Improvement in Linotype-Machines, of which the following is a specification.

In the Mergenthaler linotype-machine now in general use a composed line of type matrices and spaces is clamped temporarily between two confining-jaws for presentation to the front of the mold in which the slug or linotype is cast. In the use of the machine it frequently happens that the length of the mold is varied in order to change the length of the slug or linotype to suit the width of the column or page of print to be produced. This change in the length of the mold necessitates a corresponding change in the length of the composed line of matrices and in the distance between the confining-jaws. Heretofore the change in the distance between the jaws required considerable time and labor, owing to the fact that the movable jaw was supported by a nut on a long screw provided at one end with. an operating arm or pinion so arranged that it was necessary to release the arm, turn the screw, and again fasten the arm in order to effect the adjustment, this device being illustrated in Patent No. 436,531.

In carrying my invention into effect I avoid the usual adjustment of the jaw-supporting nut by introducing between the nut and the jaw an adjustable supporting-bar, which may be instantly adjusted to support the jaw at any required distance from the nut, and consequently at any required distance from the opposing jaw. This intermediate device may be modified in form and arrangement to any desired extent,provided it retains,essentially, the mode of action heretofore described; but I have represented it in a form which I prefer and which in practice has proven to be efficient and satisfactory. With the exception of the parts hereinafter described the machine may be in all respects in accordance with the patent above referred to and with the machines now in commercial use.

Figure 1 represents an inside face View of the clamping-jaws and attendant parts of a Mergenthaler machine with my improvement applied thereto. Fig. 2 is a horizontal crosssection on the line 2 2 of Fig. 3. Fig. 3 is a perspective view of my jaw-supporting devices.

Referring to the drawings, M represents-a portion of the stationary frame; m the stationary jaw for supporting one end of the matriX-line; m the opposing and horizontallysliding jaw for supporting the opposite end of the matrix-line; m, a horizontal screw mounted in the main frame and having at the outer end a crank-arm actuated by the vertically-reciprocating bar m, and m the nonrotating and sliding nut mounted on the screw m for the purpose of giving end support to the sliding jaw m The foregoing parts are constructed and, with the exception hereinafter noted, arranged to operate in essentially the same manner as the parts indicated by like letters in Patent No. 436,531.

The screw m instead of being made of great length, as in the original patent, is now quite short, so that it imparts to the nut m only the slight travel necessary to effect a pinching action on the line of matrices after it is introduced between the-jaws m and m The nut m instead of being arranged to bear directly against the jaw of and to travel with the jaw through its long range of adj ustment is now provided with a horizontal rod or bar A, which is adjustably secured to the nut and arranged to bear at one end against the jaw m to give the same support and hold it at the proper distance from its companion, according to the length of the matrix-line to be confined between the two jaws.

The rod or support A may be made in any suitable form; but having in view cheapness 0 of manufacture and reduction of wear I recommend the employment, as shown, of a round rod having a series of circumferential teeth a cut therein. This rod I arrange to slide freely to and fro through a horizontal 5 hole in the nut M13, and I lock it in the desired relation to the nut by means of a vertical pin B, seated in a hole in the nut and having teeth to engage those of the rod. By withdrawing this pin vertically the rod is re- :00 leased, so that it may be moved forward and backward to sustain the jawin the exact p0- sition required, after which the rod may be locked by inserting the pin, the teeth of which engage with and give firm support to those of the rod. If desired, the end of the rod may be grooved and projected into the jaw and screwed thereto by a transverse pin, as shown by dotted lines in Fig. 1, or any other similar connection between them may be employed.

The essence of the invention resides in combining with the sliding jaw and the nut an intermediate adjustable support by which the jaw may be sustained at different distances from the nut, and it will be manifest to the skilled mechanic that these details may be variously modified without departing from the limits of my invention.

Having thus described my invention, what I claim is- 1. In a linotype-machine, the combination of a sliding jaw, a screw and nut supported thereby and an adjustable connection between the nut and the jaw, substantially as described.

2. In a linotype-machine, a sliding jaw, a movable nut or support therefor, and an adjustable toothed connection between the jaw and nu t.

3. As an improvement in linotype machines, the combination of the sliding jaw or nut, its operating-screw, the toothed jawsupporting rod, and the toothed pin locking the same to the nut.

4. In a linotype-machine, the'combination of an adjustable jaw, a longitudinally-adjustable rod or bar to support the same, and a locking device engaging said bar to hold the same in predetermined positions only, whereby the jaw may be speedily set for different standard measures.

In testimony whereof I hereunto set my hand this 2d day of November, 1898, in the presence of two attesting witnesses.

JOHN R. ROGERS.
